Revised 12/21/82 <br />VEGETATION BASELINE INFORMATION <br />Visual estimates of cover were .made by looking at The <br />arrangement of species in the quadrat and estimating The areal <br />extent of each species in percent. Also, the total cover by ,all <br />vegetation, cover by litter, and cover by bare soil was <br />estimated'. To facilitate the estimates, an area equal to one <br />percent of a I.Om2 quadrat was used as a reference. <br />Two areas were set up as reference areas. Any mention of <br />control areas should be taken to mean reference area. Cover data <br />were collected during the last week of July, 1980. <br />Direction of the line-strip at each sample point was <br />determined by using a random number between I and 360. This <br />number was used as the number of degrees west of magnetic <br />north. The transect was then oriented in that direction. <br />• Semi-shrubs were defined as species which are woody at the <br />base and are mostly herbaceous throughout the rest of the <br />plant. No annual forbs were encouTered in the production <br />samples. The basis for sorting forbs was whether they were <br />annuals or perennials. This system is appropriate even if no <br />annual forbs are encountered. <br />Plate 16 in the permit application is a map which delineates <br />the vegetation types within the permit boundaries. <br />Dry Grassland <br />The dry grassland type occurs on ridges where soils tend to <br />be thin and moisture conditions are less favorable than those on <br />slopes and boTtomland areas. Mostly, these areas are too dry To <br />supoort substantial shrub development. <br />•_ <br />F-13 <br />
